For a blower car I think the best bet is to figure out a way to cut ignition. I've seen on a forum somewhere, someone claimed they had a fail safe that cut ignition. I'm not sure what could do this really. But where there's a will there's a way.

That was kind of my point. I read people say "your tuner will build in fail safes into your tune" I just don't see how with the current ECM technology with a blower. Unless you are running a waste gate there is no way to cut boost. Even if you cut timing, the car is still lean and still making boost. You can't set up some sort of over fueling strategy if you don't have the fuel available. I guess if you had a capable fuel system and purposefully leaned the car out to rely on meth then you could do it. But most guys run meth cuz they don't want to sped the ridiculous amount of money on the correct fuel systems for these cars. Like I said, I may just not know what I am doing. So for now, I will shoot for 12.5 at the leanest on pump and put in the meth for 12.0 and get out of it what I can. If it fails then 12.5 is plenty safe for a pull.
